I bought one jar last winter and thought my skin felt immediately softer after only 2 days of use. It's the only product that has kept my skin moisturized for the entire day during winter (w/o any greasy feeling or look). I only use it in the morning and use a different lighter moisturizer at night (Complex 15). It's too heavy for me to use during the summer - when I tried my skin felt too greasy. I went back to it this winter b/c it has been really dry in Northern CA and am happy I did. I slather it on b/c I know I'll just use it through the winter months and have never broken out from it. I'm usually allergic to anything with fragrance and even sometimes essential oils. This product has not bothered me and the smell is very faint. I don't even smell it anymore. My skin has gotten drier as I have gotten older (I'm 33). It probably would have been too much for me when I was in my 20s.
